- Device & OS
- not provided
- Scenario
- Setting up a booking page where clients can schedule appointments at strict 30-minute intervals.
- Observed behavior
- Bookings displays next available appointment times at odd increments like 11:05 or 11:25 instead of rounding strictly to the nearest 30-minute mark.
Log in to your Microsoft 365 admin account and ensure you have administrative access to the specific Microsoft Bookings calendar you want to configure.
Configure Time Increments and Adjust Buffer Durations
Microsoft Bookings calculates availability based on the exact end time plus the buffer. To force a 30-minute increment, the combined duration and buffer must mathematically align with your time interval settings.
If a service duration and its buffer do not sum up to a multiple of your desired interval, Microsoft Bookings will display the exact calculated time rather than rounding up to the nearest half-hour mark.
Open your Microsoft Bookings dashboard and navigate to the 'Services' tab from the left-hand menu.
Click on the specific service you want to edit to open its detail page.
Locate the 'Time increments' setting under the Scheduling policy section and ensure it is strictly set to 30 minutes.
Review your 'Default duration' and 'Buffer time' settings. Adjust these combined times so they equal exactly 30 or 60 minutes (e.g., configuring a 25-minute service with a 5-minute buffer).
Click 'Save' to apply the changes, then open your published Bookings page to verify the schedule now aligns to 30-minute increments.
Clear Browser Cache and Test in Private Window
Sometimes an outdated browser cache can cause the Bookings public page to display old availability intervals even after you have updated the backend settings.

Frequently Asked Questions
Why does Microsoft Bookings show odd start times like 11:25?
Bookings calculates the next available time slot based on the exact end time of the previous appointment plus any assigned buffer time. If your service duration and buffer don't sum to an even 30 or 60 minutes, the next available slot will fall on an odd increment.
Can I force Bookings to strictly use 30-minute intervals?
Yes, you can set the 'Time increments' to 30 minutes in the booking page settings. However, you must also ensure that your default service duration and buffer times mathematically align with this interval to prevent the system from naturally shifting the schedule.
Does clearing my browser cache fix Bookings scheduling errors?
If you have recently updated your booking intervals but the public page still shows the old odd times, clearing your browser cache or viewing the page in an Incognito window can resolve the issue by forcing the browser to load the most recent scheduling settings.
